The arms ("to be bourne ...on shields, banners and flags...") of
the province were assigned by Royal Warrant of HM King Edward VII dated 30 May
1905 (gazetted 23 September 1905), however, the original drawing was lost by
enemy action during the Second World War, and "an official drawing and
blazoning of the armorial bearings of this province granted as aforesaid"
were re-issued (this last contained in the 'Coat of Arms Act' but the date of
issue is unknown by myself)

The flag was established by 'An Act Respecting the Provincial Flag, Chapter
11, Laws of Prince Edward Island' which received Royal Assent on 24 March
1964, with the schedule therein contained describing the flag as follows:

"The flag is that part of the Armorial Bearings of the Province
contained within the shield as set out in the drawing thereof in the schedule
of the Coat of Arms Act (1988, being Chapter C10 of the Laws of Prince Edward
Island), but is of rectangular shape instead of that of a shield, with a
fringe or band hereinafter described, and measures six feet in the fly and
four feet in the hoist inclusive of the fringe or band. The Chief and charge
thereon occupies the upper one-third part and the remainder of the Armorial
Bearings occupies the lower two-thirds part of the space within the fringe or
band and the dexter of the Flag. A fringe or band of uniform depth of three
inches consisting of alternate rectangular renderings (ten inches long and
three inches in depth) of the principal colours of the Armorial Bearings
commencing with red at the top dexter runs along the perimeter of the
rectangle containing the Armorial Bearings except on the dexter. Smaller or
larger flags are to correspond with the above description in the proportions
of 6, 4 and 1/4 the fly, the hoist and depth of the fringe".

The 1988 act has been replaced by a new legislation made necessary by the
supporters etc. granted by the Governor General in a warrant dated 26. April
2002. I am unable to find an adoption date, but the coat of arms act came into
force on 13. December 2002. The new coat of arms act can be found here: http://www.gov.pe.ca/law/statutes/pdf/c-10_1.pdf

The Prince Edward Island badge according to Admiralty and Colonial Office
papers, was not approved for use on a flag until 1878. There was a design,
with a slightly off-centre crown between the two trees, that made it into
print, but probably not into cloth. There was also a suggestion that the
garland on the Lt. Governor's. version of the flag, should be rose leaves with
pink roses, but that was rejected.D Prothero - 1997-12-31

Arms

From what I can gather reading official documents available from the PEI
General Assembly web site, on 10 May 2002 Royal Assent was given to Bill No.
30, Coat of Arms Act, which added several new elements to Prince Edward
Island's coat of arms which previously consisted of a shield and a scroll
containing the motto as David described. Now the armorial bearings contain
helmet, crest, supporters, and compartment. I cannot find a representation of
these arms, it seems the Act is yet to be published. However, section one of
the Bill gives the following blazon of the full arms:

1. The Armorial Bearings of Prince Edward Island consist of the complete
armorial achievement for the Province of Prince Edward Island, being the
Armorial Bearings granted by Royal Warrant of His Late Majesty, King Edward
VII, dated 30 May 1905, as augmented by Vice-regal Warrant of Her Excellency
the Right Honourable Adrienne Clarkson, Governor General of Canada, dated 26
April 2002, and is described as follows:

(a) ARMS: Argent on an island Vert, to the sinister an oak tree
fructed, to the dexter thereof three oak saplings sprouting all proper, on
a chief Gules a lion passant guardant Or;

(b) HELMET: a helmet mantled Gules doubled Argent within a wreath of
these colours;

(c) CREST: on a grassy mount, a blue jay (Cyanocitta cristata)
reguardant crowned with the Royal Crown and bearing in its beak the leaf
of a red oak (Quercus rubra L.) fructed proper;

(d) SUPPORTERS: Two foxes (Vulpes fulva) Sable embellished Argent, that
to the dexter gorged with a collar of potato blossoms proper, that to the
